Unfortunately, your going to have to call the Manufacturer or your phone to solve this issue. The Manufacturer of your phone would be Nokia, LG, Samsung, Motorola. They are the only ones who have access to this information. Some places may charge you to get the unlock code but most won’t so it’s really hit and miss. Nokia charges 14 dollars. In this case you need to contact Samsung. I’m sorry your having so much trouble with this! I hope I was able to help you today!
Maybe your phone is locked to AT&T. I've searched the net to find the unlock codes for my fone and it worked. Search for code calculators for SGH x426. The instruction is also included in their websites. It's fairly easy.
Also, make sure that your sim is from the network provider in your country.
